Spatial Analysis was a course that explored the many ways in which data can be selected, understood and represented visually on maps in order to understand cities, spaces and places better. Through the course of this half-semester module, my aim has been to explore diverse cities through numerous lenses in order to understand variety of datasets (both types of data and different types of content), and work to exercise all possible coding muscles, even when working in groups. The ability R has to create both visually stunning and accurate maps is of importance to me and is a skill I hope to use as an urban designer, planner and researcher in the future.
This portfolio shows explorations of 5 different cities in order to demonstrate the following skills (in various permutations and combinations):
The first city I chose to explore using R was that of Chicago. Of special interest was the The Chicago Enterprise Zones Program which offers state and local tax incentives to encourage companies to locate their business in depressed areas of the city. The program aims to stimulate economic and neighborhood growth in six designated zones.
Exploring these zones through a transportation lens reveals a substantial gap in transportation investment in these zones that could limit the potential of the City’s investment in the program.
As the visualizations below illustrate, many of these zones are located in regions of the city with limited or no transit stops. For example, Zone 3, on the South Side of Chicago, one of the largest Enterprise Zones identified in the program, is not connected to any transit stop on Chicago’s ‘L’ line.
Interestingly enough, when this analysis was first undertaken to prove that Chicago’s Enterprise Zones program must consider transit access in the six zones in order to be effective, we did not have knowledge of the tidytransit package or aggregation commands we learned soon after. I believe, I can now visually illustrate this analysis in more depth, given the skillsets picked up and shown in the rest of this portfolio.
The next city of interest was that of Venice, Italy. Given the assignment - which required us to visit the Harvard Maps Collection and chose a historical map to georeference, I felt like Venice would over beautiful possibilities, which it did. Not only did we collaborate with the Maps Collection to stitch 8 panels that had never been seen together as a map, we also overlaid data about sea-level rise to render visible the effects of climate change to ourselves and others.
The most interesting insights to me were that Venice has added a lot of land mass over the last century and most of it is higher actually, thus unlikely to flood. More importantly, what was concerning was that I realized that most of the buildings that were expected to flood in a 1 meter sea level rise scenario, were public structures of historical, architectural and cultural significance.(colored in red)
